  Patent Document 1 uses a simple slit configuration to mix in a linear flow, and a high mixing effect cannot be expected. This is a technique that uses a variable slit that changes its opening according to the pressure level, and is not universal. Moreover, Patent Document 3 is merely a collision means for mixing, and is not for improving the mixing and dispersibility of the mixed fluid.

  One of the features of the present invention is based on the premise that effective and homogeneous mixing is performed using a fixed and invariant cylindrical slit nozzle diffusion mechanism. The mixed fluid derived from two different directions derived from arbitrary different positions is collided and merged by a confluence pipe, and the mixed liquid is derived from one direction using a three-way connecting pipe mechanism. Is.

  Furthermore, the present invention provides a multi-ring configuration in which the invariant cylindrical slit nozzle diffusion mechanism is superposed in multiple upper and lower stages or arranged concentrically, and the size of the slit hole of each cylindrical slit nozzle diffusion mechanism The shearing force of the mixed fluid that passes through is gradually reduced so that the mixing and dispersion can be performed at a higher level.

  The cylindrical slit nozzle diffusing mechanism according to the present invention is a slit formed between adjacent wire rods mounted in a coil shape, and the coil wire rod has a circular or sharp end face in cross-sectional shape. As a result, the opening of the slit hole promotes the work of aggregating and dividing the fluid passing therethrough, and further, after passing, has the function of promoting the function of expanding and promoting the spreading and dispersing action. Is.

Caramel sauce, pigments, sweeteners, vitamins and other liquids are the main mixed liquids, and in addition, mixed liquids containing gases containing inert gases such as nitrogen gas are included.

  Furthermore, the flow direction of the mixed fluid of the present invention has a flow path from the upper part to the lower part in the vertical direction, and the process of this flow path is dispersed and expanded by interposing a cylindrical slit nozzle diffusion mechanism. In contrast, there is a case where the flow path is formed from the lower part to the upper part in the vertical direction and the mixture is dispersed and mixed by interposing a cylindrical slit nozzle diffusion mechanism in the process.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to examples.

  First, Embodiments 1 to 4 showing the basic configuration of the present invention will be described with reference to FIGS.

  In each figure, 1 is a basic fluid storage tank for storing basic fluids such as water, milk, etc., 2 is a mixed liquid or gas, such as soy sauce, olive oil, vitamins, nitrogen gas, etc. These are mixed fluid storage tanks such as an inert gas, which are single in the figure, but two or more can also be provided.

Reference numerals 3 and 4 denote supply pipes connected to the tanks 1 and 2, which are provided with a pressurizing pump P and valves V ₁ , V ₂ , and V ₃ , and are joined to each other with a valve V _4. The supply pipe 5 is constructed so that a desired ratio of both mixed fluids can be transferred.

  Reference numeral 6 denotes a cylindrical slit nozzle diffusing mechanism, in which the mixed fluid is expanded by a conical cylinder 7 communicating with the main supply pipe 5 so that the mixed fluid can be supplied to the main cylindrical body 8.

  9 is a bottomed porous body provided on the outer periphery of the main cylindrical body 8, 10 is a long hole communicating with the porous body 9, and 11 is fixed at both ends to the outer periphery of the long hole 10. The slit-shaped nozzle body A is formed as a whole by piercing the coiled slit wire 12 with high accuracy between the adjacent wire rods (see FIG. 5).

  Reference numeral 13 denotes a mixed fluid mixing tank surrounding the cylindrical slit nozzle diffusing mechanism 6, and a discharge pipe 14 is provided at one end of the mixed fluid mixing tank 13.

15 is a return pipe provided through the valve V _5, end Yes connected to the base fluid reservoir 1 which had been reservoir basic fluid, the mixed fluid again by the action of a pump P that is interposed The basic fluid storage tank 1 for mixing is more effectively refluxed and mixed.

  The operation will be described based on the configuration of FIG.

  The basic fluid is specified and the basic fluid storage tank 1 is filled with a desired amount, and the mixed fluid is specified and stored in the mixed fluid storage tank 2.

Next, the four valves V ₁ , V ₂ , V ₃ , V ₄ are opened, a fixed amount of basic fluid and mixed fluid are supplied through the supply pipes 3, ₄ , and unprocessed mixed in the main supply pipe 5 in a mixed state. Flow fluid.

  The unprocessed mixed fluid supplied from the main supply pipe 5 is expanded in the conical cylinder 7 and expanded in the supply direction to the bottomed porous body 9 orthogonal to the flow. It is pushed into the porous body 9 provided in the circumferential direction, enters the coiled slit hole 12 equipped with the coiled wire 11 through the long hole 10, and is mixed and stirred in a state where it is also diffused in the circumferential direction. The fluid is stored in the mixed fluid mixing tank 13.

In this state, stirring and mixing are unambiguous, and in the case of a large amount of mixing, a temporary purpose is achieved, but in the case of a small amount and a small amount, it is insufficient, so the fluid in the mixed fluid mixing tank 13 is refluxed. It is preferable to pass through the slit nozzle body A of the cylindrical slit nozzle diffusion mechanism 6 again. In this case, the valve V ₁ is opened, the pump P is operated, and the valve of the supply pipe 4 for the mixed fluid storage tank 2 is used. closed V _2, the basic fluid reservoir to exert only the supply pipe 3 provided 1, only the uniquely treated mixed fluid exerts a cylindrical slit nozzle diffusion mechanism 6 in the same manner as described above complete mixing diffusion The action is performed. Then, the complete mixing state is confirmed and the operation is completed.

  In the embodiment shown in FIG. 2, the cylindrical slit nozzle diffusing mechanism 6 having the same configuration is arranged in two upper and lower stages, and if necessary, the mixing accuracy can be improved as a series configuration of three stages and four stages. it can. There is an effect that the accuracy of the mixing ratio of the mixed liquid is effectively improved by the action of the repeated mixing and stirring action of the cylindrical slit nozzle diffusing mechanism 6 continuously provided in multiple stages.

  Next, the embodiment of FIGS. 3 and 6 will be described.

  In addition, the same code | symbol is shown to what exhibits the same structure and effect | action, and the detail of description is abbreviate | omitted. Basically, the cylindrical slit nozzle diffusing mechanism 6a is different, and the rest is substantially the same. A conical portion 16 is provided in the center, and a concave groove 17 having a semicircular cross section is provided on the outer periphery of the conical portion 16 so as to divide a large number of mixed fluids flowing into the outer periphery. In the drawing, although eight concave grooves 17 are provided, the number thereof is arbitrary.

  Reference numeral 18 denotes a support rod for the slit nozzle body A arranged in a circular shape for supporting the coiled wire 11 that forms the slit hole 12 provided on the outer periphery of the concave groove 17, and the lower end of the coiled wire 11 is firmly fixed. The gap between adjacent wire rods can be formed as a highly accurate slit hole 12 (see FIG. 6).

FIG. 4 shows an example in which a multi-annular slit nozzle body A ₁ , A ₂ ,... Having a concentric circular diameter is sequentially formed on the outer periphery of the slit nozzle body A. The required number can be provided in order to increase the mixing efficiency.

It is also possible to make the slit widths of the slit holes 12 by the multi-stage slit nozzle bodies A, A ₁ , A ₂ ,. However, they may be the same without necessarily changing the slit width.

  As described above, also in the embodiment shown in FIGS. 3 and 4, the mixing action of the mixed fluid can be performed in exactly the same manner as the basic fluid as in the embodiment shown in FIGS. 1 and 2.

  By the way, in the said Example, the specific cross-sectional structure of the slit nozzle body A which comprises the cylindrical slit nozzle spreading | diffusion mechanism 6 and 6a is shown to Fig.7 (a), (b), (c), (d) and ( This will be described in detail based on e).

  With respect to the acting force of the bubble-containing liquid acting in the direction of the arrow, the configuration of FIG. 7A has an isosceles cross section, and the slit hole 12 is flat when the adjacent coiled wire 11 passes through the cross-section restricting configuration α. The configuration of the coiled wire rod 11 in FIG. 7B is a home base type, and the adjacent coiled wire rods 11 are provided with a cross-sectional aperture configuration α, and are flattened through a narrow passage shape β. It has a shape with a flat surface. Therefore, at the moment of discharging from the slit hole 12, two or more kinds of liquid components different from each other from the flat plane are separated on the average, but in the process of reaching and passing through the slit hole 12, the cross-section diaphragm configuration α As a result, the liquids adjacent to each other are polymerized so that rapid spray diffusion can be achieved.

  Furthermore, FIG. 7 (c) cuts both triangular lines and has a cross-sectional diamond shape, and the opening of the slit hole 12 is expanded to a cross-sectional trumpet shape γ. The spreading action can be promoted to increase the mixing action and work more effectively.

  7D and 7E, the cross-sectional shapes are circular and elliptical, but in this case as well, the opening of the slit hole 12 is expanded into a trumpet shape γ, so that the diagram of FIG. In the case of spray discharge that is discharged in the same manner as the configuration, the spreading action of the liquid is particularly promoted, and mixing with different liquids can be performed effectively.

  Note that (b) and (e) are provided with a narrow passage shape β in the middle, so that the mixed fluid passing therethrough is elongated, and mixing is performed more effectively by spray diffusion at the open end. be able to.

  In the above configuration, the cross-sectional shape of the coiled wire 11 is more preferably a throttle configuration α that gradually narrows on the mixed liquid introduction side in the adjacent state, and on the spray side, a trumpet-like γ that gradually expands. It has been found that the action of mixing a mixed fluid containing a gas is more effective in the configuration of.

Finally, the embodiment of FIG. 8 will be described. In the above-described embodiment, the basic fluid storage tank 1 and the mixed fluid storage tank 2, the supply pipes 3 and 4 for mixing the two tanks 1 and 2, the main supply pipe 5 and the valves V ₁ , V ₂ and V _3. since V ₄ are virtually identical, illustration is omitted.

  In short, in the previous embodiment, the configuration in which all the mixed fluids are mixed and mixed is performed from the top downward, whereas this embodiment is performed from the bottom upward. It is different. That is, the arrangement of the cylindrical slit nozzle diffusing mechanism 6a is reversed upside down and slightly different.

  The difference is that a cylindrical skirt 19 is interposed between the conical cylinder 7 and the main cylindrical body 8 to increase the overall height to regulate the flow of the mixed fluid. This is different from the cylindrical slit nozzle diffusion mechanism 6 in the example.

  Reference numerals 20 and 21 denote two opposite connecting pipes connected to the opposite positions of the lower part of the mixed fluid mixing tank 13, and 22 denotes a trifurcated three-way connecting pipe provided at the collision point of the connecting pipes 20 and 21. And it is provided with the junction pipe 23 which guides the mixed fluid supplied from two directions as one body, and the mixing action of the mixed fluid can be performed at a more active moment.

  In the figure, the three-way connecting pipe is shown as a T-shaped tube, but it can be configured as desired, such as a Y-shaped tube or a double tube.

The junction pipe 23 can be connected to the conical cylinder 7 again at the outlet opening end so as to function as a reflux pipe in the same manner as in the above embodiment. V ₆ , V ₇ , and V ₈ indicate valves provided in the connection pipes 20 and 21 and the junction pipe 23.

  In short, in this embodiment, the mixed fluid is primarily created by the cylindrical slit nozzle diffusion mechanism 6a, and then the mixed fluid in the mixed fluid mixing tank 13 is transferred from the connecting pipes 20 and 21 from two directions at the opposite positions. Since it is taken out and returned to the cylindrical slit nozzle diffusing mechanism 6a from the merging pipe 23 and further mixed by the cylindrical slit nozzle diffusing mechanism 6a, it is extremely effective for a fluid mixing operation with poor mixing efficiency.

As mentioned above, although many examples were described about the present invention, a basic fluid and mixed fluid can be specified as follows, for example.
Basic fluid: Water Milk Soy milk Fruit juice Vegetable juice Mixed fluid: Soy sauce Sesame oil Olive oil Palm oil …… Edible oil
Brewing vinegar Yeast extract Alcoholic beverages Caramel sauce Dye Sweetener Vitamin, etc. All of the above fluids are liquids. For example, when the basic fluid is to reduce or remove dissolved oxygen such as milk, the mixed fluid must be nitrogen gas or argon gas. It is also possible to prevent and improve the flavor change in other fruit juices by mixing an inert gas such as a feed gas.
